Tangshan square tube manufacturer , I will take you a minute to understand Rectangular Pipe

The definition of sharp corner square tube is: when the wall thickness is not more than 3mm, the R angle is less than 1mm; When the wall thickness is 3-8mm, the R angle is less than 2mm; When the wall thickness is greater than 8mm and the R angle is less than 3mm, this is a square and rectangular tube with sharp corners.

Sharp angle square tube, also called cold-formed steel, is a kind of rectangular thin-walled steel tube with hollow section.

Sharp corner square tube is a rectangular section size formed by cold bending and high-frequency welding with Q235 hot or cold rolled strip or coil as the base material. Its comprehensive mechanical properties, welding performance, cold and hot working performance, corrosion resistance are good, and it has good low-temperature toughness.

The production process of sharp corner square tube and rectangular tube is generally as follows:

Selection of square tube materials → acceptance of square tube materials → production of sharp corner square and rectangular tube storage devices → roll extrusion → straightening → heat treatment → mechanical property inspection → chemical analysis → tensile test of sharp corner square and rectangular tubes → warehousing of finished sharp corner square and rectangular tubes → inspection of finished sharp corner square and rectangular tubes → sharp corner square and rectangular tubes sold out in the warehouse 。
